Group hunting by killer whales for walruses was observed in August 18, 2008, in the littoral area (3 km from the haulout of walruses, Retkyn Spit, Chukotka). The group of killer whales consisted of seven adults (one adult male did not participate in attacks) and two calves. Based on prey type, these killer whales were mammal-eating. The total duration of their hunt activity was not less than 95 min. The hunt consisted of three phases. The first phase was an attack on the group of walruses and…

TLDR
The mercury concentration values in walruses from the coastal waters off the Chukchi Peninsula are lower than those obtained fromWalruses in Alaska and the Canadian Arctic.

ASSESSING KILLER WHALE PREDATION ON STELLER SEA LIONS FROM FIELD OBSERVATIONS IN KENAI FJORDS, ALASKA
The behavioral and predatory patterns of Gulf of Alaska (GOA) transient killer whales (Orcinus orca) were studied between 2000 and 2005 using remote video and vessel-based observations near the
A review of Killer Whale interactions with other marine mammals: predation to co‐existence
TLDR
It is concluded that interactions between Killer Whales and marine mammals are complex, involving many different factors that the authors are just beginning to understand.
Occurrence and behaviour of transient killer whales: seasonal and pod-specific variability, foraging behaviour, and prey handling
TLDR
Overall use of the area was greatest during that period, and energy intake at that time was significantly greater than at other times of the year, probably because of the high encounter rates and ease of capture of harbour seal pups.
DISTRIBUTION OF KILLER WHALE PODS IN PRINCE WILLIAM SOUND, ALASKA 1984–1996
TLDR
Nearshore foraging for pinniped prey by the AT1 transient whales was more common in areas where these whales spend a disproportionate amount of time, suggesting that these areas were critical foraging habitat for them.
